Alzheimer’s disease, also known as Alzheimer’s disease, has a course of roughly 5 to 10 years, with a few patients surviving for more than 10 years, and the majority of patients dying as a result of complications from Alzheimer’s disease. Alzheimer’s disease is a degenerative disease of the nervous system that occurs in old age and pre-age, and patients can experience a range of manifestations of cognitive dysfunction. In the advanced stage of the disease, as patients need to stay in bed for a long time, complications such as lung infections, urinary tract infections, and pressure sores can occur, which can lead to death in severe cases, and the course of the disease lasts about 5 to 10 years, with a few patients surviving for more than 10 years. Patients with Alzheimer’s disease can be treated with drugs such as donepezil, memantine, fluoxetine, etc. In addition, nursing care should be strengthened by giving patients medical alert bracelets and avoiding letting them go out alone. If Alzheimer’s disease is diagnosed, please follow the doctor’s instructions for treatment.
